Dugan and Spector of the WSJ take readers through efforts to push self driving technology to its limits at electric car maker Tesla. Tesla CEO Elon Musk is pushing the technology and plans to get a self driving car go from Los Angeles to New York by the end of 2017. Problems faced by Tesla include a car crash involving a driver who took his hands off the wheel of a Tesla automobile, leading to a crash with an eighteen wheeler truck. This led to an investigation by the National Highway Traffic Safety Board and a decision by Tesla to make driver's hands on the steering wheel required for autopilot to operate. Earlier in 2015 Tesla engineers confirmed that the Tesla cars were not ready for autonomous driving because of near crashes when the reliance was placed entirely on the technology. Ten engineers and two managers resigned from Tesla according to this report by WSJ, with problems relating to deadlines and marketing decisions. Sterling Anderson, the head of the Autopilot program at Tesla resigned to start his own company with the head of the autonomous driving unit at Google, saying he was going to do it the right way, citing concerns that Musk was going ahead with the technology without making it failure proof. The tricky thing about auto pilot driving is the behavioural factors involved, where drivers may take their hands off the steering wheel and not be prepared to act as a backup should the technology fail or something go wrong. Another aspect of this is the tendency of drivers not to pay attention to the road and rely completely on the auto pilot to do everything, more than its capabilities today. Toyota and other auto companies are including some elements of collision free driving, and reliable aspects of the new technology into cars. For Tesla the driverless technology is part of its marketing appeal, and CEO Musk has moved faster in this respect than his own engineering team, according to this WSJ report. ...

Toyota's views on a car run by batteries like the Volt GM has planned. It will take the time to work on this, at this time it sees a hybrid as the best option for alternate busts of power by both the electric and the gasoline power. A battery that would fill up the trunk of a car would be needed for a car to run only on electric power for 40 miles. He heads engine development and fuel cell engineering for Toyota. This is the existing technology but Toyota will take the needed time to develop the technology of lithium ion batteries to power vehicles, doing this step by step.

Interview with Honda CEO Takeo Fukui. In June Honda will rollout a new hydrogenpowered fuel cell vehicle called the FCX Clarity. Its powered with electricity produced by combining hydrogen and oxygen in batterylike fuel cells. Honda will have this vehicle available for lease this summer in California and aims to deliver about 200 of these cars by 2010. Fukui's attitude is refreshing when compared to that of other automakers when answering a question by John Murphy of the WSJ about why try to build a hydrogen car when the stations to power the cars do not exist yet. He tells Murphy if you asked were there any gas stations when Henry Ford came up with the Model T, there weren't any, lets build the cars first and the infrastructure will follow. And Honda is working on the technology that will make it possible to charge hydrogen into fuel-cell vehicles at home . He sees it happening first in California and some other states, and in Japan and Europe. And he sees it taking about 10 years to get some sort of infrastructure in place. Considering the long term nature of the demand side with the gradual inclusion of billions of people in China and India as well as Brazil and Russia into the world economy as well as people in other developing countries this is a solution that takes patient and focused development of technology which Honda is setting out to do. He does not see a safety issue in use of hydrogen vehicles as he is confident Honda can develop the expertise to handle the safety issue for hydrogen. What is his thinking on green vehicles? What happened to the Insight the first hybrid car that Honda introduced? The Insight was never intended to be a mass seller, only to establish Honda's record as having the best record in fuel efficiency. What is Honda doing in this area. Honda does see a problem in this area. Toyota he says developed a green image largely on the back of one car the Prius. Honda will come up in 2009 with a dedicated hybrid vehicle to match the Prius. And Honda is setting the bar high for this Honda hybrid, saying that his feeling that this model will have to overwhelm and overtake the Prius. He goes on to say that this is key for us. Honda he says will take on the challenge and compete with Toyota with its products, its technology, and its racing spirit. This gasoline-electric hybrid will be introduced early next year in the USA, Japan, and Europe, and it will be the first of 4 hybrid models Honda will introduce by 2015. Regarding price the company says it will be "affordable". Honda's goal is to sell 500,000 hybrid vehicles a year. Toyota aims to sell 1 million hybrid vehicles early in the next decade and is working on developing its own hydrogen fuel-cell vehicle. Is Honda developing electric cars? Takeo Fukui thinks the practical feasibility of the electric vehicle is very limited. The two biggest issues in his view being driving distance and recharging time. The FCX Clarity can be recharged in one minute, compared to the several hours for an electric vehicle. In his view the electric vehicles will be uselful only for restricted applications like golf carts. Nissan and General Motors are planning to launch electric vehicles. What is Honda's environmental strategy? Honda being a smaller company has to focus its resources wisely with strategic choices. His focus is on the hybrid as the core product, and after that comes fuel cell and clean diesel as the core products to tackle fuel eficiency and CO2 issues. Takeo has spent more than a decade on Honda's racing teams. He drives a CR-V and enjoys driving up and down the mountains, does not race but does get on Honda's test track once or twice a year. And what has he learned from all the years in racing. When he was fully engaged in the motorcycle racing teams he says the pressure was very high and if they did not do well they got bashed by managers and the media. And actually the results were disappointing for years and the teams kept losing. For hime the series of difficulties and challenges was something that he feels everyone should experience because in some ways he acquired wisdom and creativity to get through these experiences. This is some thing Honda and Fukui will need as they try to develop their own hybrid to take the lead from Toyota and come up with industry leading technology in tackling fuel efficiency and CO2 issues. His own approach to management? Two things he always keeps in mind are take time to keep up good communication with associates at work, and testing Honda's own products with his own hands. What does he think about the auto industry in 2008, is it a turning point? He says it has becom clear in 2008 that a company has to have the technology to deal with carborn dioxide and fuel efficiency issues. And its clear that smaller vehicles are more attractive than larger vehicles. And its possible he says that we may go back from automobiles to motorcycles. In fact in India Honda is promoting motorcycles in a big way, while Tata is developing the Nano for mass market, so Takeo is talking about something that Honda sees happening in some places. ...

Entergy is one of the largest energy companies. Its CEO for nine years, Wayne Leonard, talks to Joseph Rago of the Wall Street Journal. Its the No.2 generator of nuclear power in the USA, and uses coal for only 7% of its energy. He has made his name in nuclear energy, and here he talks about the government's cap and trade program and nuclear energy. He points to today's technology as far superior to the technology that was used in the Failed Three Mile plant, that put back nuclear energy plants in the USA for decades. He believes that price signals are needed for CO2, and the cap and trade program helps to do this, so he supports the cap and trade program. He admits that self interest colors perception of Entergy, compared to coal using utility producers like Duke Energy and American Electric Power. With coal only 7% in its portfolio of plants, and big in nuclear energy, it stands to gains from a cap and trade program, whereby Congress will set a ceiling on emissions, then allows businesses to sell any of its extra allowances that stand for the right to make emissions. And in doing so creating the largest commodity market, in carbon backed securiites. He and the government agree on the point that the allowances should be auctioned off, rather than given away as the companies with many coal plants believe. And the billions in new revenue from these allowances would be returned to the public. He understands that the view of companies like Duke and AEP, that use coal and would have to increase rates, and face the anger of ratepayers as they pay more for the allowances. He also thinks the bill should be written with a fine pen, so that if Congress mandates 20% of energy come from renewables. That it should specify replacing coal not natural gas as what this replaces, to get rid of the most polluting sources. He points to the real need for looking at things globally, as doing things locally, even to show responsible leadership in the world community, can lead to no progress in the global picture. The reason is that China is going ahead with the rapid construction of conventional coal plants. It has surpassed USA coal capacity, and is on track to double it sometime in the next decade. If the USA closed down every single coal plant, and all the time new coal plants are going up in China and India, then we would have ruined our economy, and it was'nt making much difference globally. And he says, if we just say lets lead and people will follow us, "its silly", because China isn't going to follow us, especially when they have $2 trillion invested in their coal plants, and they still aren't feeding feeding all their people. So how to deal with this? Develop the new technology for carbon capture for existing conventional coal plants, and help the Chinese with retrofit technology to curb emissions in a realistic manner. At this time most current funding is devoted to technology for second generation systems, that are still 10-20 years away....

The Japan Automobile Dealer's Association says Toyota's Prius hybrid was No. 1 in sales in Japan in 2009 with 209,000 sales, three times the sales in 2008. This shows the high popularity of green cars in Japan and a sign of future trends. Hybrid sales made up 10% of new vehicle sales in Japan in 2009. By comparison hybrid sales in the U.S. were 2.8%. Second in car sales in Japan was the Honda Fit, third the Toyota Vitz, both small fuel efficient cars. About 1.6 million Prius cars were sold worldwide from 1997 to 2009, according to Toyota. Toyota has kept the price of the Prius affordable by pricing it at around $22,000.

Revised auto fuel efficiency standards win the support of GM, Ford, Chrysler, Honda and Hyundai. These standards would lower the average fuel economy to 54.5 miles per gallon by 2025, a decline from the initial target of 56.2 mpg. The revised proposal calls for a 5% average annual increase in fuel economy for cars and a 3.5% increase for light trucks through 2021. After 2021 both cars and trucks have to meet a 5% annual increase. Useful innovation in the new standards is to provide credits for hybrid pickup trucks, and give credits for technological advances that improve fuel economy but don't show up in EPA tests such as the one that shuts of the engine when a car is idling. Other credits would be offered for solar roof panels on electric vehicles. It includes incentives for "promoting early market penetration of tailpipe CO2/fuel consumption reducing technologies." This comes after a long period in which the U.S. lagged behind other countries in fuel economy. It could be one of the main achievements of the Obama administration, and help build a new auto industry around new technologies....

Controversy about whether bringing back a revamped Ford Explorer is a good idea. Ford's Farley thinks Americans might still consider an Explorer with high fuel economy, getting it up to 28 mpg from 15 mpg. But the evidence is that Americans have soured on SUV's. Consider that during the cash-for-clunkers program more Explorers were scrapped, and by a large margin, than any other model. Sales are down from 450,000 at one time to 52,000 today. To get buyers to look at the Explorer Ford is trying to change the looks from boxy to sleeker car-based crossover , and add high tech features. In fact it is going to be built not as an SUV, but on the same architectural base as the Taurus.

The critical exchange between oil companies and auto companies about who is at fault for the energy crisis. In one ad that ran last year, Chevron argued that "if automakers improved fuel economy across the board by just 5 mpg, we'd save over 22 billion gallons of gasoline a year." The criticism is also sparked by the high price of oil which is hurting sales of pickups and large SUV's that the automakers depend on for profits. One ad by Exxon Mobil shows a cartoon of a large SUV filling up at a gas station and hints that the problem rests with the automakers who have failed to build the kind of highly fuel efficient vehicles that are needed. The ad says that the average fuel economy of new U.S. autos has not gone up much in two decades, the small gains have been offset by the increases in the size and weight of vehicles.

Fuel efficiency rules require average fuel efficiency in the U.S. of 35 mpg by 2016. The debate is now on what to do for 2017 to 2025. New technology such as the P2 systems for hybrids already used in VW, Nissan and Hyundai vehicles makes a 20% increase in fuel efficiency possible. Large investments are being made to bring new technology to bear on increasing fuel efficiency significantly. Government agencies are looking at different scenarios by which the new fuel economy standards beyond 2017-2025 could be set between 47 mpg and 62 mpg. An additional factor is the reduction in greenhouse gas emissions- at 47 mpg the reduction would be 3%, at 62 mpg the reduction would be 6%. Another factor is how much the impact is on the cost of vehicles and reduced cost on gasoline. Here there is a wide range in the numbers for average mpg rules at 62 mpg- with EPA estimates at $2800-$3500 increase in vehicle cost and $5000 savings in fuel cost, Centre for Automotive Research estimates at $9790 increase in vehicle cost. The 62 mpg translates into "real world" actual efficiency of 45 mpg. In April 2011, 17 senators put out a letter of support for the 62 mpg proposal. There is a public value involved in this that is also significant- the reduced dependence on foreign oil means savings in defense expenditures in parts of the Middle East, and an economy that is less impacted by volatility in the price of oil. As this aspect of public value or benefits cannot be quantified easily even though they are significant, this may tend to be lost in the debate and the politics of fuel efficiency. For automakers there is significant marketing value in having a visible and strong presence in fuel efficient vehicles because of perception as forward looking- something that hurt Detroit carmakers in the last decade. During periods of gasoline prices at $5 a gallon this provides carmakers with an extra cushion of safety in securing car sales. Carmakers in one country such as the U.S. also have to worry about what carmakers in other countries such as Japan and Germany are doing- if the standards in the U.S. develop a gap compared to other countries developing advanced fuel efficiency technologies this poses significant risks because of the global nature of the automobile marketplace. See the group "Asleep at the Spigot" for more details on this. Many of these less quantifiable factors do not get the attention they deserve because they are significant from experience but not easily quantified. Throw into this the large unknown of what new technologies not yet developed lie ahead with a burst of effort by one country or another, which bring cost reductions at the same time - and the debate requires as much a good sense of what is the path offering the greatest advantages in years ahead than a pure exercize in numbers. ...

A major change is taking place. Automakers around the world are shifting to smaller engines. Hyundai's Sonata for 2011 and the Tucson crossover for 2010 are going to have only 4 cylinder engines. Many V-6's offered by Detroit carmakers are being replaced with 4 cylinder engines and V-8 with V-6 engines. Ford is using the EcoBoost a turbocharged V-6 to offer new options for its Taurus, Lincoln MKT and other cars.
